HYDROCARBON-FILTER.

SPECIFICATION forming part of Letters Patent N 0. 723,556, dated March24, 1903.

Application filed October 18,1902.

To all whom, it may concern:

Be it known that I, GEORGE W. STEWART, a citizen of the United States,and a resident of Ticonderoga, in the county, of Essex and State of NewYork, have invented a new-and Improved Hydrocarbon-Filter, of which thefollowing is a full, clear, and exact description.

My invention relates to hydrocarbon-filters,

my more particular object being to produce a neat, cheap, and compactfilter admit-ting of general use, and especially applicable to launches,automobiles, and other machinery, in connection with gasolene-engines.Preferably the filter is located at some point between the gasolene-tankand the needle-valve.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter-fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my filter, oer-- tain parts being brokenaway. Fig. 2 is a central section at right angles to the view shown inFig. 1, and Fig. 3 is a horizontal section upon the line 3 3 of Fig.2looking toward the bottom of the bulb.

The bulb 1 is provided with a cavity 2 and with inflow and outflowpassages 3 and 4. At the bottom of the bulb is a discharge-passage 5,normally closed by a screw-plug 6. This plug is provided for the purposeof removing any residual products which may be stopped by the filter andalso for renewing the filtering material placed within the bulb. Mountedcentrally within the bulb and preferably integral therewith is a web 7,provided with holes 8, extending toward the discharge-outlet 5, beingseparated from the plug 6 by a hiatus 9. This arrangement allows theresidual products to be readily discharged by merelyunscrewingtheplugfi.Mounted within the top of the bulb and preferably integral therewith isa thickened portion 10, provided with a screw-socket 11, engaged by ascrew 12, as indicated more particularly in 50 Fig. 2. A gauze-netting13, preferably of a generally semicylindrical form, is fitted into .bedesired to admit the air.

Patent Serial No.127fl64. (No model.)

one-half of'the bulb, as shown in Fig. 2. A filling consisting,preferably, of fibrous materialsuch as cotton, curled hair, or silkfiber 14-is disposed between the web 7 and one of the walls of the bulb."This filling is preferably inserted through the dischargeaperture 5, asabove explained. By means of the holes 8 and the hiatus 9 the web 7 mayengage the material practically throughout the en tire length thereof,and yet permit free passage of the liquid through and under the web7that is to say, if the web 7 were not provided with the holes 8 itslength would have to be curtailed in order to allow free passage of theliquid beneath it, and this ourtailment of the length of the web wouldrender the filling l4 comparatively insecure. A pair of air-passages 15and 16 are connected with the screw-socket 11 and also with the cavityof the bulb, as indicated in Fig. 2. By this means comm unicatio'n maybe established between the cavity upon either side of the web 7 and theouter atmosphere, the screw 12 being removed for this purpose wheneverit may The passages 15 and 16 thus serve as a vent which is normallyclosed, but may be opened at will.

It will be understood, of course, that not only will the sediment andimpurities of va- 8o rious kinds be removed by the filtering material,but all heavy substance contained within the hydrocarbon will collect atthe bottom and may be discharged. For instance, if the hydrocarboncontains water the same may be extracted independently of the action ofthe filter proper.

At thebeginning of the operation and as often thereafter as desired thescrew-plug 12 is removed, so as to allow the bulb to fill withhydrocarbon liquid, after which the plug is replaced.

Having thus described my invention, I claim as new and desire to secureby Letters 1. As an article of manufacture, a hydrocarbon-filtercomprising a hollow bulb provided with inflow and outflow passages, ascrew-socket intermediate of said passages, and a pair of air-passagesconnecting said screw-socket with said inflow and outflow passages, saidbulb being further provided with J a web having openings and disposedwithin said bulb at a point intermediate of said inflow and outflowpassages, a filtering material disposed within one-half of said bulb andengaging said web, and a screw-plug for engaging said screw-socket,thereby closing said air-passages.

2. As an article of manufacture, a hydrocarbon-filter comprising ahollow bulb provided withinflow and outflow passages, and

with a web disposed intermediate of the same and further provided with athreaded socket and with air-ducts in communication with said socket andwith the chamber of said bulb, and a screw-plug for detachably engagingsaid screw-socket.

3. As an article of manufacture, a hydrocarbon-filter comprising ahollow member provided interiorly with-a central web havingperforations, and also with inflow and outflow passages, said memberbeing further provided with a pair of ducts for admitting air upon bothsides of said web, a fastening for opening or closing said duetssimultaneously, and means for removing residual products lodged withinsaid hollow member.

through the same, and a screw-plug for normally closing the saiddischarge-passage.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE W. STEWART.
